be除了做谓语动词还可以做什么

如题所述

  be动词意思和用法很多,一般的意思是:是,此种用法,有多种变化形式,is,am,are,was,were,being,been,to be.另外,be动词还有成为的意思。根据句子中不同的人称、数和时态,应该选择相应的be动词。

    “Be”除了原形的“be”之外,还有另外七种形式:am, is, are, been, being, was, were.在句子中,“be”可以是主动词(The Principal Verb)或助动词(The Auxiliary Verb). 
    当主动词时,“be”在性质上属于接系动词(The Linking Verb), 后面要有名词、形容词、地方副词或短语作补足语(The Complement).例如:

    The man is a science teacher. 

     Mary's new dresses are colourful. 

    “Be + 现在分词”以组成进行式时态(Continuous Tenses),如:

  3. Tony's maid is washing his new car.

  4. The children are playing in the field.

    “Be + 过去分词”以组成被动语态(The Passive Voice),如:

  5. Her money in the drawer was stolen.

  6. A lot of good jobs are taken up by foreigners.
